Fifteen healthy adults (eight males) volunteered.<\/p>\n<p>Following a 15-minute baseline period, participants were immersed in 42\u00b0C water and passively rested until their rectal temperature was raised by 0.5\u00b0C above baseline. Thereafter, they were immersed in a different water tank maintained at 12\u00b0C water temperature until their rectal temperature was decreased by 0.5\u00b0C below baseline. This procedure was conducted twice. Auto-Regressive Integrated Moving Average analysis showed that fluctuations in finger blood flow were associated with changes in mean body temperature (Ljung-Box statistic &gt;0.05; R\u00b2 = 0.67) and body heat storage (Ljung-Box statistic &gt;0.05; R\u00b2 = 0.70), but not with rectal (Ljung-Box statistic &lt;0.05; R\u00b2 = 0.54) or tympanic (Ljung-Box statistic &lt;0.05; R\u00b2 = 0.49) temperatures.<\/p>\n<p>It is concluded that reflex alterations in finger blood flow during repetitive hot and cold water immersions are associated with mean body temperature and the rate of body heat storage, but not with rectal and tympanic temperatures.<\/p>\n<p><span style=\"color: #000000;\"><strong>Full Text Link: <\/strong><\/span><\/p>\n<p><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21166926\/\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/pubmed.ncbi.nlm.nih.gov\/21166926\/<\/a><\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-8302 size-full\" src=\"https:\/\/www.famelab.gr\/wp-content\/uploads\/2021\/11\/Line.png\" alt=\"\" width=\"1316\" height=\"1\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>Flouris AD, Cheung SS.
